----------------------------------------------------------------------------------

The Conference on Optimization and Information Systems (COSI) aims to bring together researchers in Computer Science and Mathematics, primarily from the fields of combinatorial optimization, graph theory, information systems, and artificial intelligence. The 17th edition of COSI, taking place in Bejaia from 01 to June 03, 2025, will be hosted by the Ecole Supérieure en Sciences et Technologies de l'Informatique et du Numérique (ESTIN - Bejaia). This edition follows previous ones held in Tizi-Ouzou (2004), Bejaia (2005), Algiers (2006), Oran (2007), Tizi-Ouzou (2008), Annaba (2009), Ouargla (2010), Guelma (2011), Tlemcen (2012), Algiers (2013), Bejaia (2014), Oran (2015), Setif (2016), Bouira (2017), Oran (2018), and Tizi-Ouzou (2019).
COSI fosters a friendly and engaging environment for discussions and exchanges between researchers. Continuing its tradition, the 2025 edition will feature high-profile invited talks, original research papers, and demonstrations of research prototypes.
 
We invite submissions in two categories:
1. Regular papers (up to 12 pages, LNCS format)
2. Demo papers (up to 4 pages)
All submissions must be in PDF format and electronically submitted using the Microsoft Conference Management Toolkit (CMT) via the following Submission Link : https://cmt3.research.microsoft.com/COSI2025 
Guidelines for formatting (number of pages, LaTeX and Word styles) can be found here : https://cosi.isima.fr/cosi2025/soumettre.php  

All accepted and presented manuscripts will be included in the online conference proceedings. 
We are currently on discussion with Springer to publish COSI-2025 post-proceedings in the CCIS series of Springer. CCIS Series is Indexed in DBLP, Google Scholar, EI-Compendex, Mathematical Reviews, SCImago, and Scopus. CCIS volumes are also submitted for inclusion in ISI Proceedings.
